Ignition & Electrical Upgrades

Your engine's power is limited by what your ignition system can reliably deliver. A misfiring cylinder under boost isn't an inconvenience — it's a blown head gasket waiting to happen. Performance ignition upgrades fix the spark side of the equation: higher-energy coil packs that fire cleaner under high-compression and forced induction conditions, spark plugs gapped and heat-ranged for your specific application (street plugs run hot to self-clean; racing plugs run cold to survive boost), and wiring harnesses that don't introduce resistance and noise into your signal chain. We stock spark plugs across SBC, BBC, SBF, Pontiac, and Mopar fitments in iridium, platinum, and racing compounds — including NGK, Autolite, AC Delco, and Champion. Match the heat range to your compression ratio and fuel type, not just your engine family. The Garage guide walks through plug selection in detail — read it before ordering if you're on boost or high-compression.
